Metabolism

/məˈtæbəlɪzəm/noun

The whole set of chemical reactions by which a living body turns food into energy, tissue and waste.

The Greek roots

μετά
metá
across, beyond
+
βάλλω
bállō
to throw, cast

Literally: a throwing across, change

The story of the word

Metabolḗ was Aristotle's ordinary word for change of any kind, one state thrown across into another. Nineteenth-century physiology narrowed it to the chemistry of a living body, and English took the term from German in 1878. The two halves came later: anabolism for the building up, catabolism for the throwing down, both still carrying bállō, to throw.
